Abstract

A method for operating a primary unit that exchanges information with at least one secondary unit, including the following: ascertainment by the primary unit of a first number of primary measured values, in particular measured values of an entropy source shared with the secondary unit; reconciliation by the primary unit of the first number of primary measured values, in particular with a corresponding number of secondary measured values that have been obtained by the secondary unit, to obtain reconciled primary measured values, the secondary measured values having been obtained by the secondary unit in particular from the shared entropy source; and application by the primary unit of a secret-sharing method to share secret data with the secondary unit, the secret-sharing method being executed as a function of the reconciled primary measured values.
